Description
The LUMIMATS group is composed of researchers and professors experts in molecular spectroscopy, computational chemistry, and materials chemistry. The team has vast experience in the photochemical and photophysical study of homogeneous and heterogeneous photoactive systems, as well as in the synthesis, functionalization, and characterization of hybrid materials. Our laboratory is equipped with high-resolution photophysical techniques that enable the analysis of light absorption and emission in different states with time resolution from picoseconds to milliseconds across the UV–visible–NIR range. This combined experimental–theoretical approach is applied to the design and development of multifunctional dyes and materials for light-driven applications in areas related with health and energy.

Equipment
- UV-Vis-NIR spectrophotometers (CARY 7000 and CARY 3000, Agilent Technologies) for solid and liquid samples, with accessories for temperature control and advanced measurements of absolute transmission and reflection under different polarization and incidence angles (UMA)
- Spectrofluorometers (FLS 920 and FS5, Edinburgh Instruments) with picosecond resolution and NIR sensibility, integrating sphere, polarizers, temperature controller, cryostat for 77K.
- Flash photolysis (LP980, Edinburgh Instruments) for transient absorption (ns scale) and stimulated emission under Nd:YAG laser coupled to OPO system LOTIS (TII 2134) for excitation at UV (355 nm, 100 mJ) and Vis/NIR (410-2000 nm) at 1-10 Hz
- Optical microscopes: Fluorescence microscope (Olympus BX51) coupled to a spectrofluorometer, and confocal time resolved (PicoQuant Microtime 200).
- Infrared spectrophotometer (FTIR, Nicolet iS50, Thermo Scientific) for middle and far IR, with accessories: Attenuated Total Reflection (ATR); diffuse reflectance (DRIFT); Grazing-angle reflectance (GA-FTIR), VEEMAX III.
- Cyclic voltammetry (Metrohm Autolab) adapted with miniaturized vessels and electrodes for measurements at low volumes (2 ml).
- Laminar flow cabin (Cruma 670FL) and orbital shaker-incubator (Grant-bio) for Bacteria culture biotests
- Theoretical simulations with access to EHU (ARINA) and DIPC (Atlas EDR/FDR, Hyperion) high-performance computing clusters.
